The Garmin Forerunner 405CX updates the Forerunner 405, increasing accuracy in heart rate-based calorie computation. Using algorithms developed by exercise scientists and world-class athletes, the Forerunner 405CX monitors the micro changes in a user’s heart rate and uses that detailed information to better calculate the number of calories burned during aerobic activity.
Another new thing — the 405CX comes with two additional form-fitting bands to accommodate large or small wrists. Like the Forerunner 405, the 405CX brings features not found on the earlier Forerunner 205 and 305 models:
- For one thing, the style has changed, with a sleeker and more watch-like appearance.
- A wireless connection, using ANT+Sport technology, sends data to your computer. No more cables!
- The touch-sensitive bezel minimizes the need for buttons on the unit.
- The map screen found on previous Forerunners is gone (it was pretty rudimentary anyway, showing only waypoints and tracks). But hey, who are we kidding? The Forerunner 405 is a runner’s training partner, not a navigation device.
